🔍 What Happened?

The Lawsuit

The case was filed in the U.S. District Court for the Northern District of California by authors Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson. The plaintiffs alleged that Anthropic engaged in "large-scale copyright infringement by downloading and commercially exploiting books" obtained from pirated datasets.

The Core Issue

The lawsuit centered on Anthropic's use of two specific databases:

• Library Genesis (LibGen)

• Pirate Library Mirror

These are known repositories of pirated books that Anthropic allegedly used to train its Claude AI models.

The Settlement Terms

• Payment: Approximately $3,000 per book, plus interest

• Eligible Authors: Around 500,000 writers qualify for compensation

• Dataset Destruction: Anthropic agreed to destroy all datasets containing the allegedly pirated material

• Timeline: The case was scheduled to go to trial in December 2025 before the settlement was reached

⚖️ Legal Background

June 2025 Ruling

In a significant preliminary ruling, a judge determined that Anthropic's use of books to train AI models qualified as "fair use." However, the judge ordered a trial to specifically examine whether the company infringed copyright by obtaining works from the pirated databases Library Genesis and Pirate Library Mirror.

This distinction became crucial: the method of acquisition, not just the use of the material, was under scrutiny.

Settlement Announcement

On September 5, 2025, Anthropic announced the settlement agreement. On September 25, 2025, a federal judge granted preliminary approval to the settlement, moving it one step closer to finalization.
